1/ What' s a server error; what/who causes them? A " 501 Internal Server Error" is a general internal server error. Your web browser is making a request of the web server, like " please show me this page" or " I' ve pushed this send button, please execute this script" or a similar request. A " 501 Internal Server Error" is the server saying " I' m sorry, I tried to do what you want, and I for some reason, I can' t." This can mean a script is incorrectly configured, or the server hasn' t found something it needs. Again, it' s a very vague, general error message. It' s quite different from a " 404 Page Not Found" message, which at least tells you the specific problem -- the web server cannot find the page requested. What does it mean when a server times out? Again, we have the scenario where your browser is making a request of the server -- show me a page, execute this script, return this database information. Because a server will be managing huge numbers of requests all at the same time, it will have a " time out" setting for various functions. It may dedicated 30 seconds to trying to send your email, or 90 seconds to trying to fill your database request. After that, it gives up on what you asked for, dumps your request and deals with other pending requests. What are server extensions? Are they different than FrontPage extensions? Server extensions are installed on a server to support something specific with it' s own special web server bits. Normally, extensions are part of a development environment -- like FrontPage. However, there can be other kinds of server extensions, like ColdFusion. So, FrontPage extensions are a kind of server extension. Because this site is mainly FP, we tend to just refer to " server extensions" and assume everyone is talking about FrontPage ones. What' s recalculating a web? See below. What' s recalculating hyperlinks (can do this via FrontPage)? FrontPage has a feature that will let you recalculate the hyperlinks in a web. That means that it will look at your FP web and update some of it' s paths if it' s got it' s knickers in a twist. If you FTP a web up to a server, for example, it may not recognise changed paths for webbots like page counters; recalculating the links live on the server will fix that.
